Apomixis, asexual reproduction through seeds, has the potential to revolutionize agriculture if its genetic basis can be elucidated. However, the genetic control of natural apomixis has remained obscure until quite recently, owing to all the complications of Mendelian genetics, such as epistatic gene interactions, components that are expressed sporophytically and gametophytically, expression modifiers, polyploidy, aneuploidy, segregation distortion, suppressed recombination, etc., that seem to have accumulated during the evolution of apomixis. In this review we show how molecular markers and superior phenotypic methods have been used to clarify the genetics of apomixis in monocots as well as dicots during the past 15 years. Many of the complexities in the genetics of apomixis are likely secondary and have evolved as a consequence of the reproductive process. New mapping techniques, such as comparative mapping, linkage disequilibrium mapping, and deletion mapping, and new high-throughput sequencing methods, will help to penetrate the core of apomixis chromosomal regions. If the evolutionary genetic load can be exposed and removed, the apomixis genes may be used in agriculture as a tool to fix elite genotypes.

植物无融合生殖的孟德尔遗传学。

如果可以阐明其遗传基础，则无融合生殖是通过种子无性繁殖的，它有可能彻底改变农业。然而，由于孟德尔遗传学的所有复杂性，例如上位基因相互作用，孢子和配子体表达的成分，表达修饰子，多倍性，非整倍性，分离畸变，抑制的重组，直到最近，对自然无融合生殖的遗传控制仍保持模糊等等，似乎在无融合生殖的进化过程中积累了。在这篇综述中，我们展示了过去15年中如何使用分子标记和卓越的表型方法来阐明单子叶植物和双子叶植物无融合生殖的遗传。无融合生殖遗传学中的许多复杂性可能是继发性的，并且由于生殖过程而演变。新的作图技术，例如比较作图，连锁不平衡作图和缺失作图，以及新的高通量测序方法，将有助于穿透无融合生殖染色体区域的核心。如果可以暴露和消除进化的遗传负荷，则无融合生殖基因可以在农业中用作修复优良基因型的工具。
